Kübler Sport® Rocking Blocks, set of 12

The wooden blocks make stacking a little tricky. Due to their special shape with 18 or 20 sides and differently sized contact surfaces, the blocks can be combined on top of each other in a standing or lying position until the tower is so wobbly that the structure collapses. Constructing requires skill and dexterity.
